Newton's Cradle in Vacuum
Name: Chris S.
Will a Newton's cradle run longer in time from start to
finish, in a vacuum chamber? Due to no air resistance and energy lost in
the form of sound when the balls collide.
Just as a Newton's cradle runs for less time in water, I expect it would
run quite a bit longer in a vacuum. Still, it would not run forever. Some
energy can work its way through the strings into the support and then into
